Iscar 6405253 Grooving Insert GIPI318020P IC8250 Carbide

Product Description

The ISCAR 6405253 is a solid carbide grooving insert carrying the GIPI318020P designation and IC8250 manufacturer grade. It is designed for external grooving and parting operations on CNC lathes and turning centers. The insert features a 0.1252-inch (3.18 mm) cutting width, a 0.0079-inch (0.20 mm) corner radius, and an Al2O3 PVD coating that improves wear resistance and edge retention under high cutting speeds. The neutral hand orientation and double-end design extend usable tool life. A positive rake angle of 8 degrees and P-style chip breaker support efficient chip control in demanding turning applications.

This insert is suited for grooving and cut-off operations in both production and job-shop environments. Primary workpiece materials are stainless steel and steel, corresponding to ISO material codes M and P. The Cut-Grip series uses a clamp holding method compatible with ISCAR Cut-Grip toolholders and blade-style holders designed for that system. It is a multi-use insert appropriate for precision grooving where consistent width and radius control are required.

Installation Notes

Installation is performed by a machinist or toolroom technician on a lathe or turning center. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate ISCAR clamping screw and torque driver specified for the toolholder — do not overtighten with general-purpose tools. Inspect the insert pocket and clamping surfaces for chips or damage before seating the new insert to ensure proper contact and runout.
